How did you ask your BMs if they would be your BM?

How did you ask your bridesmaids if they would be in your bridal party? Email, phone, cards? Any other creative ideas? And besides that what is the proper etiquette? I have my best friend, 2 neices and sister. I was just MOH for my sister in August.

I asked my girls on the phone. My MOH(s) - I am having two - are my sister-in-laws. And my lone BM is a good friend from college. She's the only one from the circle of college friends able to travel to Belize...so once I found out she was able to attend I asked her if she would stand up with me. I didn't want to ask before I knew she was going so I did not add any pressure into her decision making.

OMG!!! that is perfect. I really want to steal that. How awesome!! Mine are scattered about the country and i am not sure i have enough time to ask them that way - but i am soooo going to do that or something similar after i ask them.

My Matron of Honor was with me dress shopping and I had not asked either of them yet....and she says "so who are you having as your MOH?" She thought is was going to be my cousin so she just asked.....we had stopped for lunch at McD's and were eating chix nuggets! We will laugh about that forever I imagine.

I made both the girls cards to "officially" ask them...I used the same poem! I am a scrapbooker, so I made the cards and printed the poem with their names in them. The girls loved them....
